Abstract

A security monitoring system including; an exit and entrance camera located at the exit and entrance of a structure; a detector for detecting the exit or entry of an individual; an image recording system for stroring images from the exit and entrance cameras; and a computer vision system for analyzing the stored images using a predetermined criteria to determine if the exiting and entering individuals are the same. In a preferred implementation, the system also includes a database for storing face image data for each authorized individual of the structure; and a face recognition system for comparing the stored images from the entry and entrance camera with the stored image data in the database and for determining if the exiting and entering individual is one of the authorized individuals.

Claims

1. A security monitoring system comprising;

an exit and entrance camera located at the exit and entrance, respectively of a structure;

a detector for detecting the exit or entry of an individual into or from the structure;

an image recording system for storing images from the exit and entrance cameras; and

a computer vision system for analyzing the stored images transmitted from the image recording system using a predetermined criteria to determine if the exiting and entering individuals are the same.

2. The security monitoring system of claim 1, wherein the detector is a door contact sensor located on an exit/entry door of the structure.

3. The security monitoring system of claim 1, wherein the detector is an infra-red sensor located near an exit/entry door of the structure.

4. The security monitoring system of claim 1, further comprising means for transmitting an alarm signal if the exiting and entering individual is determined not to be the same.

5. The security monitoring system of claim 1, further comprising means for transmitting at least a portion of the stored images to a remote site if the exiting and entering individual is determined not to be the same.

6. The security monitoring system of claim 1, wherein the predetermined criteria used to determine if the exiting and entering individuals are the same comprises matching descriptive features of the entering and exiting individual.

7. The security monitoring system of claim 6, wherein the descriptive feature is selected from a group consisting of one or more of a color, shape, or texture distribution of the stored images.

8. The security monitoring system of claim 1, further comprising:

a database for storing image data for each authorized individual of the structure; and

a recognition system for comparing the stored images from the entry and entrance camera with the stored image data in the database and for determining if the exiting and entering individual is one of the authorized individuals.

9. The security monitoring system of claim 8, wherein the stored image data in the database are face images and the recognition system is a face recognition system.

10. The security monitoring system of claim 8, further comprising means for transmitting an alarm signal if the exiting and entering individual is determined not to be the same and the exiting and entering individual is determined not to be one of the authorized individuals.

11. The security monitoring system of claim 8, further comprising means for transmitting at least a portion of the stored images to a remote site if the exiting and entering individual is determined not to be the same and the exiting and entering individual is determined not to be one of the authorized individuals.

12. The security monitoring system of claim 1, wherein the image recording system stores the images from the exit and entrance cameras upon the occurrence of an event.

13. The security monitoring system of claim 12, wherein the occurrence of an event is the triggering of the detector.

14. A method for performing security monitoring of a structure, the method comprising the steps of;

capturing images at both an exit and entrance of the structure;

before or after the capturing step, detecting the exit or entry of an individual into or from the structure;

storing the captured images; and

analyzing the stored images using a predetermined criteria to determine if the exiting and entering individuals are the same.

15. The method of claim 14, further comprising the step of transmitting an alarm signal if the exiting and entering individual is determined not to be the same.

16. The method of claim 14, further comprising the step of transmitting at least a portion of the stored images to a remote site if the exiting and entering individual is determined not to be the same.

17. The method of claim 14, further comprising the steps of:

storing image data for each authorized individual of the structure; and

comparing the stored images from the entry and entrance with the stored image data for determining if the exiting and entering individual is one of the authorized individuals.

18. The method of claim 17, further comprising the step of transmitting an alarm signal if the exiting and entering individual is determined not to be the same and the exiting and entering individual is determined not to be one of the authorized individuals.

19. The method of claim 17, further comprising the step of transmitting at least a portion of the stored images to a remote site if the exiting and entering individual is determined not to be the same and the exiting and entering individual is determined not to be one of the authorized individuals.

20. The method of claim 14, wherein the storing step stores the images from exit and entrance cameras upon the occurrence of an event.
